Good stuff! But I take exception to this statement. Human hardware is finite, even if massively parallel.
The computing hardware that we keep inventing and improving is not limited. Recent advances in quantum computing use the fabric of the universe.
My real point is that human hardware is not advancing, but manmade hardware is. And at an exponential rate. It is not about if, but when AI will be equivalent to human intelligence.
And after that we'll be left in the dust.

“Human hardware is finite”
In the respect that it might not be changing much, sure, but how it operates is still unknown, so we cannot say it is finite. How much it might be changing is difficult to tell since we have a few thousand years at best worth of data on that.
